Specification of Letters Patent.

Patented Aug. 1, 1916.

. Appli-cation filed December 21, 1915. Serial No. 67,974.

To all 'whom t may concern:

Beit known that I,` DANIEL J. DUNBAR, a citizen of the United States, residing at Philadelphia, inthe county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements'fin Sashes, of which the following -is a specifi# cation. f My invention relates to improvements in sashes, and more particularly to improved vmeans for securing the glass pane ln-the frame, so that the joint will be strong, du-y rable, and practically air tight, and prevent all movement of the pane in the frame.

A further object is to provide a sash which can be manufactured at a reasonably' low price, and which permits the ready re moval of a broken pane, and the substitution of .a new one whenever required.

With these and other objects in View, the invention consists incertain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings: Figures,v

l and 2 are views in elevation of opposite sides of a window sash embodying my improvements, and Fig. 3 is an enlarged view in section on the line 3 3 of Fig'. 1.

l, l, represent the vertical stiles connected by horizontal rails 2, 2, forming a frame supporting a sash pane 3.. Inside of the" sash frame formed by stiles l, and rails 2, I secure a glazing frame 4 which comprises four metal strips 5 secured together at their ends by solder, or otherwise con# nected to form a frame which neatly fits within the sashand is secured by nails 6.

Each strip vis bent'longitudinally forming an inner leaf 7 .and an outer leaf 8. The inner leaf 7 is relatively flat and is secured', against the stiles of rails ofthe sashbyA nails 6 or other suitable securing devices. The

louter leaf 8 is of general curved form, and

at its edge bears against the sash pane 3.

AS shown clearly in 3, the qleaf 7 projects y inwardly a distance beyond the edge of leaf S, or in other words, a distance at least equal to the thickness of the pane 3. It will alsoV be noted that the pane 3.at' its edge is spaced slightly from the leaf 7, so that a filling of -plastic material 9 in the strip bears against the edge of the pane as well as against the face of the pane, and constitutes a Seal to render the sash air tight.

Iusethis term plastic material to cover cement, putty, or any similar material which can be used ina plastic state .and which afterward hardens and I have found by experiment that .cement answers the purpose very effectually.

The pane 3 is securely held `against the glazing frame 4 by glazing strips 10 which yare secured to the stiles and rails of the sash vby nailsv 1l. These glazing strips 10.are preferably of wood and they can be easily removed from time to time to permit a broken pane to be replaced.v

In constructing the sash, the glazing frame 4 is first secured by means of its nails 6, and the plastic material 9 is inserted in the glazing frame. The pane 3 is then pressed into the plastic material 9 until its movement is stopped by the free edge of leaf S, when it will be notedthat the edge of the pane will be embedded in the plastic material, and after the strips l0 are secured, the sash will be air tight.

It will be noted that the leaf 7 is sufflciently long to accommodate the plastic material 9 at the edge of the pane 3, and that I utilize the difference in length of leaves 7 and S to properly locate the pane and house the plastic material.

Various slight changes might be made in the general forln and arrangement of parts described without departing from my invention, and hence I do not limit myself to the precise details setforth, but consider myself at liberty to ymake such changes and .alterations as fairly fall `within the spirit and scope of the appended claims.

I-Iaving thus described my invention, whatI claim as new and desire to secure by Letters Patent is:

l. The combinationwith a main sash frame, of a. glazing frame secured in the sash frame, saidglazing frame comprising metal strips bent forming two leaves, one leaf of each strip relatively flat and coinci dent with a surface of the main sash frame and secured to said surface, the other leaf curved and shorter thanthe first-mentioned leaf, plastic material in the glazing frame, and a pane positioned-against the edge of the curved leaves of the frame strips and embedded in the plastic material, substan tially as described.

2. The 'combination with a main sash frame, of a glazing frame secured in the sash frame, said glazing frame comprising metal strips bent forming two leaves, one leaf of each strip relatively flat and coincident With a surface of the main sash frame and secured to said surface, the other leaf curved and shorter than the firstnmentioned leaf, plastic material in the glazing frame, and a pane positioned against the edge of the curved leaves of the frame strips and embedded in the plastic material, said plastic material locatedbetween the edge of the pane .and the first-mentioned leaves of the strips, substantially as described.

3. The combination with a main sash frame, of a glazing frame secured in the sash frame, said glazing frame comprising metal strips bent forming two leaves, one leaf of each strip relatively flat and coincident with a surface of the main sash frame and secured to saidlsurface, the other leaf curved and shorter than the first-mentioned leaf, plastic material in the glazing frame, and a pane positioned against the edge of the curved leaves of the frame strips and embedded in the plastic material, and detachable glazing strips secured in the frame and holding the pane against the glazing frame, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

DANIEL J. DUNBAR.
